To {1J/Z 1072/0772, t may concern:

Beit known that I, PHILO L. FOX, a citizen of the United States, residing at Bridgeport, county of Fairlield, State of Connecticut, have invented a new and usei ul Adjustable and Separable Square and Miter, of which the following is a speciiication.

This invention has for its object to provide a simple and inexpensive implement consisting only of a single sliding blade and a detachable handle which shall combine all the functions of an ordinary steel square-that is, used as an inside square, an outside square, &c. with those of a miter, and shall be adapted to be taken apart and packed in the smallest possible compass for shipment or to be carried about in a tool-box, as it requires very much less space than any implement of its class now upon the market.

Vith these and other objects in view I have devised the novel, adjustable, and separable square and miter of which the following description, in connection with the accompanying drawings, is a specification, reference characters being used to indicate the several parts.

Figure 1 is an elevation illustrating my novel implement as in use as an outside square Fig. 2, a plan view illustrating its use as a miter; and Fig. 3 is a section on the line 3 3 in Fig. 1.

My novel square and miter consists simply i of a single sliding blade (indicated by 10) and an adjustable handle, (indicated by 11,) with means for detachably and adjustably securing the blade to the handle. The face of both ends of the blade are preferably squarethat is, at right angles to the sides, as at 12. Near one end of the blade is a longitudinal slot 14, by means of which the blade is 'attached to the handle. The operative end of the handle is a miter, as at 15-that is to say, the face of the end of the handle lies at an angle of lforty-five degrees to a line crossing the handle at right angles to the sides. At the operative end of the handle is a transverse slot 16, lying in the direction of its width, which receives the blade, the edge of the blade resting against the bottom of the slot, which may intersect or lie slightly below, as preferred, the lower end of the miter at the end of the handle.

17 indicates a longitudinal slot intersecting the transverse slot which receives a locking-rod 18. This locking-rod is threaded at its inner end, as at 19, is cut away on one side, as at 20, to receive the portion of the blade below the slot, and is provided at the end opposite to the thread with an undercut head 21, which is adapted to pass through the slot in the blade, the undercut face of the head being adapted to engage the lower wall of the slot.

22 indicates a knurled nut on the rod, which lies in a recess 23 in the handle and which when tightened up against the wall of the recess draws the blade tightly against the base of the slot in the handle and locks the parts securely together.

24 indicates bridge-pieces across the slot in the handle, which may or may not be prof vided on one or both sides of said slot and which provide additional bearing-surface for the nut when turned down on the lockingrod to lock the blade in place.

The operation is as follows: To remove the blade, the nut is turned backward on the locking-rod sufliciently to permit the undercut head thereon to be swung out of the slot in the blade, which leaves the blade free so that it may be removed. This swinging movement is permitted by the open-side slot which presents no obstruction to such movement. When it is simply required to adjust the blade, the nut is only turned backward sufficiently to loosen the blade slightly so that it may be moved longitudinally in the slot in the handle in either direction. Having given to the blade the desired adjustment, it is locked in place again by tightening up the nut. When the slotted end 12 of the blade is in alinement with the long side of the handle, the implement is adapted 'for use as an inside or outside square or any of the ordinary uses of a steel square, and when the. blade is passed outward beyond the long side of the handle, as in Figs. 1 and 2, the implement is adapted to any of the Various uses of smaller squares, as tool-box and benchsquares.

When it is desired to use the implement as a miter, the miter end 15 of the handle is placed against the work, as indicated in Fig. 2, the line 25 indicating the work. When the implement is placed in this position relative to any ',[ixed edge, the outer edge of the blade (indicated by 26) will be an outside miter and the inner edge of the blade (indilOO cated by 27 will be aninside initer, one blade being used for either purpose described without removing it from the handle.

Having thus described Iny invention, I claim- 1. A square and Initer comprising a handle having at one end an inclined face to serve as a miter, in the direction of its width a transverse slot and a longitudinal open-side slot, a blade lying in the transverse slot and also provided with a slot7 a locking-rod lying in the longitudinal slot and having an undercut head adapted to engage the Wall of the slot in the blade, threaded at its opposite end and cut away on one side to receive the blade below the slot and a nut on said rod for locking the blade in place. A

2. A square and Initer comprising a handle having in the direction of its width a transverse slot, and formed with a longitudinal open-side `slot with a bridgepiece at the lower end thereof and having a recess below said bridge-piece, a blade lying in the transverse slot and also provided with a slot, a locking-rod lying in the longitudinal slot and having a head adapted to engage the wall of the slot in the blade and a nut on said rod engaging the wall of the recess and the bridgepiece7 whereby the blade is locked in place.

In testimony whereof I aHX :my signature 3o in presence oi two Witnesses.
